What happens here

This segment differentiates between Skil's impact wrenches and impact drivers. The impact wrench (with a 1/2-inch square drive) offers higher torque at a slightly lower speed, ideal for heavy-duty fastening like lag bolts. The impact driver (with a 1/4-inch hex chuck) provides higher speed with slightly less torque, suitable for driving smaller fasteners like hex screws or shorter lag bolts. The presenter also touches upon brushless motor technology, explaining that it allows the tool's motor to respond dynamically to demand, drawing power from the battery only when needed, which improves efficiency and prevents bogging down under load.

Goal: Explain the differences between impact wrenches and drivers, and the benefits of brushless motors.

[Music] [Applause] what are we lickin Eric we have the world's first cordless worm drive from SkillSoft 48 volts of power you can rip through pressure-treated anything all day long tons of power and the juice to get the job done every day when did this come out just came out September 2019 and this is certified in Canada - yes yeah all North America so we've actually got an impact wrench versus an impact driver what's the fundamental differences because this kind of gets can be confusing can it okay I mean quick rundown okay with the impact wrench you're gonna have a higher torque range and slightly lower speed impact driver slightly higher speed and maybe it's slightly under with the torque purely related to the fact that here you're driving things with a quarter inch hex and here you're driving things with a half inch bullnose so we're driving things it's like this lag bolt versus a care exactly so you need two different tools you know so you're gonna have a much higher range off of this tool and torch than this tool but then you're gonna have higher rpms from this tool so it's a question of balancing efficiency you just choose the tool depending on your application thank you I want everybody else to hear this so with brushless technology yes the motor explained this to me like give me the ten second over okay so the whole thing is you need to draw as much power out of the battery as you can and when your tool demands power you can't just have to have the motor balk down under any circumstance so a the battery's
